CaMoO 4: Dy 3+ used as solid-state laser single crystal, which operate in the yellow region, have important technological applications. In this paper, based on the crystal-field theory, the optical spectra of Dy 3+ in CaMoO 4 crystal are calculated by diagonalizing the 42 × 42 energy matrix. The electron paramagnetic resonance (EPR) parameters g factors g‖ and g⊥ and hyperfine structure constants A‖ and A⊥ of 161 Dy 3+ and 163 Dy 3+ isotopes in CaMoO 4 crystal are investigated using the perturbation formulas of the 4f9 ion in tetragonal symmetry. The needed crystal parameters are determined from the superposition model and the local structure of the studied system. The calculated results are in good agreement with the experimental values.
